Description

Schneider 8536SCO3H626S Magnetic Motor Starter

Product Overview

The Schneider Electric / Square D 8536SCO3H626S is a NEMA Size 1, 3-pole non-reversing AC magnetic motor starter from the Class 8536 Type S family. It is designed for starting, stopping, and protecting 3-phase AC electric motors.

This specific configuration features an open-type panel-mount design equipped with a TeSys T solid-state / electronic motor management controller (LTMR) integrated into the assembly, providing advanced motor protection, monitoring, and fieldbus communication capabilities.

Key Specifications

Key Advantages

• NEMA Standard Durability: Heavy-duty Type S design built to withstand high operational frequency, electrical spikes, and mechanical wear.
• Advanced Motor Management: Integrated electronic overload/TeSys T controller offers highly precise thermal modeling, phase loss/imbalance detection, and real-time current monitoring compared to traditional bimetallic thermal units.
• Separate Control Circuit Flexibility: Allows the control coil circuit to operate independently from the main motor line voltage for enhanced safety and PLC integration.
• Modular Repair & Maintenance: Contact blocks, coils, and overload units can be individually replaced or serviced without dismounting the entire starter chassis.
• Cabinet Optimization: Open-style frame is tailored for installation inside custom switchboards, Motor Control Centers (MCCs), or OEM industrial enclosures.

Important Installation & Usage Precautions

• Enclosure Requirement: As an Open Type starter, it has no built-in IP/NEMA protection against dust or water. It must be installed inside an appropriate IP54/NEMA 1, 4, or 12 control cabinet.
• Overload Controller Parameterization: Prior to initial startup, configure the FLA (Full Load Amps), trip class, and communication parameters on the electronic overload controller to match the connected motor’s nameplate data.
• Separate Control Wiring: Pay close attention to the separate control circuit wiring (“S” suffix). Ensure control voltage supply matches the installed coil voltage rating before energizing.
• Short-Circuit Protection: The starter provides overload protection only. Branch short-circuit and ground-fault protection (such as molded case circuit breakers or class J/RK fuses) must be installed upstream according to NEC guidelines.
• Safety Isolation: Always disconnect and lock out all main and control power sources before performing installation, wiring modifications, or contact inspection.

Applications

• Industrial Motor Control Centers (MCC): Standard component in custom MCC assemblies for process plant automation.
• Heavy Machinery & OEM Equipment: Used for 3-phase motor control in large pumps, industrial fans, blowers, and air compressors up to 10 HP.
• Manufacturing Line Drive Units: Direct-on-line control for heavy conveyors, agitators, packaging lines, and material handling systems.
• Smart Factory Integration: Used where network communication and granular motor health diagnostic data are required back at the PLC/SCADA level.
